Annular vantages in view, the invention r :3 club To all whom it may concern:

Be it known that 1, JOHN A, Lament, Jr., a citizen of. the United States, residing at Brooklyn, in the county 0i. Kingssa, Satate oi New York, have invented certain new and useful Improvements in Automatic Train Stops; and I do hereby declare the follow ing to be a full, clear, and exact ,description ofthe invention, such. as will enable others skilled in the art to Which it appertains to make and use the same. i

This invention relates to new and useful improvements in automatic train stops, and is particularly directed to the provision of a device adapted to be positioned aloi'ig a track, and preferably operated in connection With a conventional visual signal to actuate certain mechanism carried by the train "for stopping the same.

It is generally the object of the present invention to improve the structure and eificiency of train stopping devices of this character, and to this latter end it is more particularly the object to provide such train carried mechanism, which when actuated by mechanism along the track Will operate in a sufliciently slow manner to assure proper manipulation of the air valves or other stopping means utilized.

With the ahove and other objects and ad-- esides more particularly in the novel comb ation, "formation and. arrangement of parts as more fully hereinafter. described and pointed out in the appended claims. p

Reference is had to the accom any-ting. drawings wherein similar characters of reference designate corresponding parts throughout the several views, and in which;

Figure 1 is a view in plan of the train stopping device l 2 is nal sectional view therethrough, and, is a transverse sectional. view taken on. the line 3-3 of Referring; now more particularly to the accompanying drawings, 5 designates a pair of tracks and 6 a suitable visual signal mechanism.

The improved device includes relatively long permanent magnet Y, which is secured on a bar 8 extending," longitudinally between the tracks and having its ends jourualed in suitable bearing blocks 9, A Wire 10 so cured to the her, and a second Wire 11 also secured thereto and. trained therearound a ation of Fietters Patent.

extended with the Wire 10, these Wires being preferably connected to or otherwise operated by the Wires actuating the visual signal, this being; effected in any desired manner, Thus upon actuation of the visual signal the magnet will be moved to either lie in inoperative position or in operative raised position to en go a suitable armature momher carried a the train. This armai' inembeii' comprises an iron block 12 'WlllC s suitably held under the train in a detach able manner, as by the hook arm 13, so that when it passes over the magnet 7 in raised position it will be drawn from said arm and c to the A shaft Yielis carried a: 1L .1 tie; y train, and secured. on shaft is spool 15 on which is wound a c nsiderable length of Wire 16 having one end secured to the armature. The shaft 1 L alsocarries a. Worm gear 17 of relatively low pitch "which meshes with a pinion 18 formed on a shaft 19 Which is operatively connected in any desired manner to the air and throttle valve mechanisms of the train to actuate them to stop the same. By this construction, the Wire 16 which is unwound from the spool at a comparatively great speed, r0- tates the shaft 14 at such high speed that it could not he directly connected to the train control mechanism, but by the provision of the low pitch Worm gear, the motion is re duced to adapti or actuating the said cont; l mechan' a,

in the op magnet '4 is swung on the rod 8 to a raised oroperative position, a train passing there-- over will have its armature 12 slip oi? the hook 13 and cling to the magnet, thus unwinding the Wire on the spool and causing the shaft 1% to be rotated with a correspondins; transmission of its motion to the train. control mechanism as described. A simple mes has thus been provided for reducing the motion imparted parts of a moving train by means positioned along the track, whereby the train control mechanism may be automatically operated. by means positioned along the track when the train is'moving therepast at a relatively high speed lVhat I claim is:

i, In a train control, the combination of a shaft, a second shaft, gear men s connecting; said shafts and adapted to rotate the second shaft at speed. a length of flexible material WGUlld on the First shaft,

and means at the end of the cable engageable' by a stop arranged on the track to unwind the cable.

i 2. In a train control, the combination of a shaft-,a Worm gear on the shaft, a second shaft adapted to actuate the'control mechanism of a train, a gear on said second shaft meshing with the Worm gear, a length of flexible material Wound on the first shaft, and means at the end of the cable engageable with a stop arranged on the track to un- 1 wind the cable.

3.- In a train control, a magnet adapted to be disposed along a track, an armature adapted to be detachably carried by a train, a shaft carried by the train, a flexible member secured to the armature and Wound on the shaft, and means including a reducing train of gears for actuating the control mechanism of a train upon rotation of the shaft.

In testiinony whereof, I afiix my signature, in the presence of two Witnesses.
